IMPRUVENIENT IN CUNDENSERS 0R CUULERS FDR ALCHOLIC AND OTHER LIQUIDS.

Specification forming part of Letters Patent No. 119,942, dated October 17, 1871.

To all 'whom it may concern:

Be it known that I, JAMES R. NEIL, of Brooklyn, in the county of Kings and State oi' New York, have invented an Improvement in Coolers or Oondensers for Fluids; and the following is declared to be a correct description thereof.

This improvement is especially designed for condensing` alcohol; but it may be employed for condensing or cooling fluids or liquids of any character.

The vapor or iiuid is admitted into a chamber near the middle thereof, and within this chamber is a septum with perforations or openings at or near the e lge, and the vapor or fluid passes away from nearlhe center, so that a circulation of such uid or vapor is maintained contiguous to the walls of the chamber and cooled or condensed by the temperature at which such walls are maintained. In this manner a large extent of cooling surface is obtained within a small space, and the apparatus is chea to construct, not liable to become injured by ex ansion or contraction because the connections from one chamber to the other are at the centers of the chambers, and the metal can expand or contract freely around the same.

In the drawing, Figure l is a vertical section of two of the said chambers, and Fig. 2 is a partial sectional plan.

Ooncave disks a and b, of suitable size, set together in pairs, form the cooling or condensing'- chambers c. These disks are to be of greater or less concavity according to the thickness of the metal and the strength required. The chambers are connected together by couplings e, and a series of suchcooling or condensing-chambers connected together form the apparatus with a capacity proportioned to the number of chambers employed. Within each chamber c is a septum, el, made preferably convex, and around the edges of the same are the passage-ways Ai 11 for steam or vapor. I have shown these passageways as made by a row of holes, but slots may be employed if desired.

In this construction the vapor or liquid to be condensed or cooled is made to travel contiguous to the inside surfaces of the disks a and b so as to become cooled; and I remark thatthis apparatus is to be immersed in water to reduce the temperature of the same to a proper degree.

I claim as my invention- The septum d between the concave disks a and b and within the chamber c, in combination with the inlet and outlet connections e near the center of the disks, and the passage-ways i z near the edges of such septum el, as and for the purposes set forth. l

Signed by me this 31st day of May, A. D. .1871.
